Build Coal Forge

The coal forge is an old cast-iron sink is transformed into a forge with a novel design - an integrated quench tank. Assembled entirely from discarded materials, this forge consists essentially of an old vacuum-cleaner motor and blower, and a cast-iron sink. The dimensions given may be altered to suit the material at hand. The air for the coal forge is divided at the blower. Half of the air is diverted up the stack to keep the shop clear of smoke, and the rest for the coal. The original strainer in the sink serves as the tuyere iron, and a 1 in. street elbow connects the sink with the draft pipe. The sink hood itself is made from a single piece of sheet metal. The addition of brackets and a "douse" tank completes the forge.
